PDHB [ENSP00000307241]
pyruvate dehydrogenase (lipoamide) beta; The pyruvate dehydrogenase complex catalyzes the overall conversion of pyruvate to acetyl-CoA and CO(2). It contains multiple copies of three enzymatic components: pyruvate dehydrogenase (E1), dihydrolipoamide acetyltransferase (E2) and lipoamide dehydrogenase (E3)
PDHX [ENSP00000227868]
pyruvate dehydrogenase complex, component X; Required for anchoring dihydrolipoamide dehydrogenase (E3) to the dihydrolipoamide transacetylase (E2) core of the pyruvate dehydrogenase complexes of eukaryotes. This specific binding is essential for a functional PDH complex
Evidence suggesting a functional link:
Neighborhood in the Genome:   None, but homologous genes are neighbors in other genomes (score 0.792).  
Gene Fusions:   yes (score 0.015).  
Cooccurence Across Genomes:   yes (score 0.370).  
Co-Expression:   yes (score 0.279). In addition, putative homologs are coexpressed in other species (score 0.343).
